There was an equal mix of nostalgia and excitement during the Skybound Energon panel at San Diego Comic Con on Saturday afternoon. Onstage you had the writers of G.I.Joe and Transformers, Joshua Williamson and Daniel Warren Johnson (who is also handling art duties), respectively. Alongside these creators were Skybound's Editor in Chief Sean Mackiewicz and founder Robert Kirkman rounding out a line-up of creative minds who have deep connections to these properties that they loved as children.
